Abstract
PURPOSE: To obtain the continuous reproduction output by giving the control to several magnetic head output signals which are the intermittent signals via the switching means or the like.
CONSTITUTION: The FM aural signals obtained through rotary heads 3 and 4 are applied to switches 12 and 13 via reproduction amplifiers 10 and 11. Switches 12 and 13 feature the different phases at the switching time and function to complement the dropout of signals to each other. Accordingly, the output have no dropout at the switching time although the phase is discontinuous. The output of FM demodulators 16 and 17 are applied to switch 18, and have the noise generated when the signal phase is discontinuous. Switch 18 is changed over between the switching points of switches 12 and 13 to function to avoid the noise generation, and the output of switch 18 is delivered to output terminal 20 through deemphasis circuit 19. In such way, the continuous reproduction output can be obtained.
